<h2>Moving Wet Objects with Wrinkled Fingers</h2>

<h3>Description</h3>

<p>Results from an experiment to move wet/dry objects with wrinkled/dry fingers
</p>


<h3>Format</h3>

<p>A data frame with 80 observations on the following 7 variables.
</p>

<dl>
<dt><code>Participant</code></dt><dd><p>Participant ID  (<code>p1</code> to <code>p20</code>)</p>
</dd>
<dt><code>Time</code></dt><dd><p>Time to move objects (seconds)</p>
</dd>
<dt><code>Condition</code></dt><dd><p><code>non-wrinkled/dry</code>, <code>non-wrinkled/wet</code>, <code>wrinkled/dry</code>, or <code>wrinkled/wet</code></p>
</dd>
<dt><code>Fingers</code></dt><dd><p>Status of fingers (<code>non</code> or <code>wrinkled</code>)</p>
</dd>
<dt><code>Objects</code></dt><dd><p>Status of objects (<code>dry</code> or <code>wet</code>)</p>
</dd>
<dt><code>WrinkledThenNon</code></dt><dd><p>Wrinkled first? (<code>1</code>=yes or <code>1</code>=no)</p>
</dd>
<dt><code>DryThenWet</code></dt><dd><p>Dry first? (<code>1</code>=yes or <code>1</code>=no)</p>
</dd>
</dl>



<h3>Details</h3>

<p>Each of 20 participants were measured doing a &quot;transfer task&quot; several times under each of four conditions. The transfer task was to pick up an item with the right hand thumb and index finger, pass the item through a small hole and grab it with the left hand, and then put the item into a box that had a hole in the lid. Sometimes the participant's fingers were wrinkled; sometimes the items were sitting in water.
